使用的MAC，Idea 使用过程中总是无法联网正常下载依赖使用。
今天终于怀疑到是代理问题，进入Preferences -> HTTP Proxy 显示如下：
文字描述如下：
You have JVM property “socksProxyHost" set to “127.0.0.1”.
This may lead to incorrect behaviour. Proxy should be set in Settings | HTTP Proxy
This JVM property is old and its usage is not recommended by Oracle.(Node: It could have been assigned by some code dynamically.)
在网上找了几种方案尝试了下，如下方案解决了我的问题：
System preferences -> network -> Ethernet or wifi -> Advanced -> proxies, uncheck proxy you have enabled before.
忘了自己什么时候把全局 的网络设置设置了默认代理，或者可能是其他软件设置的吧！
在此记录分享给大家，也便于自己以后查询。

Book Description
Anyone who knows software development knows about the
Java
Virtual Machine (
JVM
), it is responsible for interpreting
Java
byte code and translating it into actions. In the beginning,
Java
was the only
pro
gramming language used for the
JVM
. However, increasing the complexity of the language and im
pro
ving the performance of the
JVM
created an opening for a new generation of
pro
gramming languages.
If you want to build a strong foundation with the
JVM
and get started with popular modern
pro
gramming languages, then this book is for you. It begins with a general introduction to
JVM
and the features common to the
JVM
languages, helping you keep abreast of its concepts.
It then dives into explaining languages such as
Java
, Scala, Kotlin, Clojure, and Groovy. It shows you how to work with each language, plus their features, use cases, and the
pro
s and cons. By writing example
pro
jects in those languages and focusing on each language's strong points, we will help you find the
pro
gramming language that is most ap
pro
priate for your particular needs.
By the end of the book, you will have written multiple
pro
grams that run on
JVM
and know about the differences between the various languages.
What you will learn

解决修改以太网配置后立即断电配置丢失问题因为以太网配置结果是保存在本地文件中，当设置完成后立即断电，文件还在缓存中，并未真正写到磁盘，所以会导致配置丢失。这里在修改配置完成后增加磁盘同步，强制文件写入磁盘，从而解决断电配置丢失问题。
二、Android支持多摄像头
某些平台默认只支持2个摄像头，但随着 AI 越来越热门，图像识别应用越来越广泛，我们经常需要用到更多的摄像头

JVM
_ARGS是用于设置JMeter的
Java
虚拟机参数的命令。通过设置
JVM
_ARGS，可以为JMeter提供额外的
Java
虚拟机参数，以满足特定的需求。
在Windows系统中，可以通过修改jmeter.bat文件来设置
JVM
_ARGS。在jmeter.bat文件中，添加如下配置：
```shell
set
JVM
_ARGS=%
JVM
_ARGS% -Dswing.plaf.metal.controlFont=Dialog-32
set

_ARGS=%

JVM
_ARGS% -Dswing.plaf.metal.userFont=SansSerif-20
set
JVM
_ARGS=%
JVM
_ARGS% -Dswing.plaf.metal.smallFont=SansSerif-20
在Linux和Mac系统中，可以通过修改jmeter.sh文件来设置
JVM
_ARGS。在jmeter.sh文件的开头添加下一行：
```shell
JVM
_ARGS="-Xbootclasspath/p:..."
请注意，具体的
JVM
参数设置可能因系统和需求而异。上述示例仅为演示目的，您可以根据实际情况进行相应的修改。
